Qauv:
Pre insulated PVC yeeb nkab yog tsim los ntawm PVC ua hauj lwm yeeb nkab (los yog PP-R, PE-RT, PB), rwb thaiv tsev txheej, thiab txheej tiv thaiv yeeb nkab.
1.Cov yeeb nkab ua haujlwm yog cov kav dej siv rau kev xa xov xwm.
2.Polyurethane rwb thaiv tsev txheej yog cov khoom siv rwb thaiv tsev tsim los tswj qhov kub ntawm qhov nruab nrab thauj los ntawm cov kav dej.
3.Qhov kev ua haujlwm ntawm lub raj tiv thaiv sab nrauv yog txhawm rau thaiv qhov kev puas tsuaj thiab cuam tshuam ntawm sab nraud quab yuam thiab ib puag ncig ntawm cov khoom siv rwb thaiv tsev.
Pre insulated PVC yeeb nkab yog ib yam tshiab ntawm rwb thaiv tsev pipeline nrog zoo rwb thaiv tsev kev ua tau zoo, kev nyab xeeb thiab kev ntseeg tau, thiab tsawg engineering nqi. daws cov teeb meem rwb thaiv tsev thiab dej tsis zoo ntawm PVC polyurethane ua npuas ncauj rwb thaiv tsev kav rau 75 degree high-temperature heat transfer hauv nroog centralized cua sov. PVC polyurethane ua npuas ncauj rwb thaiv tsev cov kav dej tsis yog tsuas yog muaj qhov tsis sib xws ntawm kev ua haujlwm thiab kev ua tau zoo piv rau cov kav dej thiab cov kav dej, tab sis kuj tseem muaj txiaj ntsig zoo rau kev lag luam thiab kev lag luam, thiab tseem muaj kev ntsuas muaj zog rau kev txuag hluav taws xob thiab kev txuag hluav taws xob. PVC polyurethane ua npuas ncauj rwb thaiv tsev yeeb nkab yog sib txuas nrog rau sab nraud ntawm PVC yeeb nkab vim yog polyurethane zoo npuas rwb thaiv tsev txheej, uas thaiv cov infiltration ntawm huab cua thiab dej, thiab muaj peev xwm ua si lub luag hauj lwm zoo rwb thaiv tsev. Nyob rau tib lub sijhawm, nws lub qhov ua npuas dej raug kaw, thiab nws qhov nqus dej tsawg heev.
Thaum PVC cov kav dej kub rwb thaiv tsev yog faus rau hauv av, kuj tseem yuav muaj kev cuam tshuam sab nraud ntawm cov av uas tshwm sim los ntawm axial hloov chaw. Nyob rau tib lub sijhawm, muaj qhov siab tshaj plaws, uas feem ntau tsis ua rau muaj kev cuam tshuam loj heev. Txawm li cas los xij, thaum lub siab tshaj plaws kev ntxhov siab dhau los ntawm kev hloov pauv, nws tuaj yeem ua rau deformation thiab puas hauv cov kav dej.
Thaum PVC cov kav dej kub rwb thaiv tsev tau muab faus rau hauv av, vim tias cov av tsis sib xws, lub siab hauv cov kav dej yog me me thiab yuav tsis muaj kev puas tsuaj. Txawm li cas los xij, qhov kev hloov pauv kub yog qhov loj, thiab qhov kev puas tsuaj ntawm cov kav dej kuj tseem ceeb heev. Yog li ntawd, nyob rau hauv kev tsim cov kav dej, lub cyclic yas deformation thiab qaug zog deformation tshwm sim los ntawm qhov kub thiab txias yuav tsum tau txiav txim siab, thiab yog li ntawd, yuav tsum tau them nyiaj mloog mus rau lub zog ntawm cov kav dej.
